Mulch:

Pine bark nuggets

Mulch of coarse fraction is most suitable for plantings with large-size plants, such as for use around decorative shrubs and coniferous trees. It should be remembered that coarse mulch should be laid in a thicker layer, otherwise there will be undesirable crevices and holes between large pieces of bark, in which weeds can be sown, and then germinate afterwards. This type of mulch is perfect for a playground, a garden path, or simply as a decorative material that simultaneously serves as a support layer. In the end, until now nothing was created more like land in a pine forest.

Pine bark mulch - medium fraction (1st sort)

This is the most versatile kind of mulch. Mulch of the middle fraction is aesthetically attractive, because it consists of separate, easily discernible pieces of golden brown bark. In addition, it is effective: due to the small size of the particles, allowing them to fit tightly to each other, it covers the soil in a dense layer, keeping moisture and temperature in the soil well. Medium size mulch also easier disintegrates in comparison with mulch of coarse fraction. This kind of mulch can be used for plants of any size, it is ideal for perennials. Mulch should be laid with a layer of not less than 5-7 cm in thickness, and every year the layer needs to be renewed, adding at least 1 centimetre, as the mulch disintegrates over time, enriching the soil with humus.

Pine bark mulch - fine fraction

Such mulch of fine fraction provides the best coverage of soil and perfectly enriches heavy clay soil, improves water absorption, stability of humidity and soil temperature, provides processes of biological activity and increases the content of natural minerals. The fine mulch mixed with the soil makes the soil more friable, improving the circulation of air in it. The particle size allows the mulch to decay quickly enough, enriching the ground with humus. Plantings can be mulched with two kinds of mulch - mulch of coarse and fine fraction. In such a case, at first a layer of fine mulch is laid on the soil to decay, as well as to promote the activity of microorganisms and improve the structure of the soil. In turn, the coarse mulch is laid out as a second layer, due to which sharp temperature fluctuations in the upper layers of the soil are reduced, protection of the plant roots from frosting is provided, as well as dirt entry is prevented when it rains.

Pine bark mulch - MIX

Mulch of this type contains fractions of all sizes and is suitable for plants of all kinds. The fine fraction will settle on the ground and disintegrate, promoting the activity of microorganisms and improving the soil structure, while the coarse fractions over small particles will reduce the sudden temperature fluctuations in the upper layers of the soil, protect the roots of the plants from frosting and prevent dirt from entering when it rains. 

What is mulch:

Mulch is a specially prepared organic or inorganic materials used for covering the soil surface around plants and beds of rows, as well as track, play areas and paths lining. Mulch fulfils both decorative and practical functions ensuring favourable growth conditions for plants and preventing from weeds growing. Depending on the raw material and its structure, there are distinguished different types of mulch.

Organic mulches are the materials of plant origin that gradually decay in soil contributing organic matters thereto and increase its fertility. The most frequently used organic mulching materials are bark mulch, wood chips, sawdust, pine cones, peat, compost, straw, leaves and cut grass mass. In turn, inorganic mulch originates from inanimate nature, and this category include a variety of rock tops, for example, tumbled pebble, gravel, decorative stone, pottery fragments, brick and stone chips as well as synthetic materials - agrofilms, geotextile, mulching films. Sometimes, large vegetable farms also use cut rubber or plastic mulch, but this method is considered to be harmful to the nature and, therefore, undesirable.  

Every type of mulch has its own optimal scope of use. For example, synthetic materials - agrofilms, mulching film, are mainly used for producing horticulture. They effectively prevent from weed growing and retain moisture for a long time, but it is visually unappealing. Also, in steep slopes, where the light organic mulch can’t hold, the inorganic material such as pebbles or decorative stones will fit better. However, unlike organic materials, the inorganic materials will have not practical use in soil enrichment.  
Organic mulching materials not only perform weed control and moisture retention functions, but also protect plant roots from temperature fluctuations and black frost, and enrich the soil with mould humus. However, almost every organic mulching material has its own pros and cons. For example, peat is not effective for weed suppression, but is useful for soil improvement and help to keep soil moisture, if it is applied to at least 10-15 cm thick layer. Wood chips are quite coarse material, which decomposes more slowly than bark mulch and often contain a dye, so it is usually used in small areas where there is a special design effects are achieved by combining different colours. Sawdust is the cheapest, but the least popular mulching material because, if packed, its particles prevent water penetration in the soil; moreover, decaying it consumes a lot of nitrogen. Grass cuttings, straw, leaves are more practical than decorative mulching materials and are available seasonally. In autumn they can be spread out beneath trees to enrich the soil with mould humus and protect the roots from frost-killing, however, be wary of the plant contamination with weed seeds.  
Thanks to its excellent decorative and practical qualities, the most popular and the most widely used organic mulching material is pine bark mulch. This mulch is made from chopped and sieved pine bark and is available of three fractions: smaller, medium and larger sized. Pine bark mulch shall be laid in at least 5 cm thick layer, and about 1 cm layer shall be replenished each year, because the mulch decays with the time and mixes with soil. Fine pine bark mulch is excellent for soil improvement - by mixing it with the soil, soil friability and good air permeability is ensured. 

Technology:

"Aggregare" Ltd. production facilities are located in Sējas region. The plant is equipped with modern equipment, packaging lines and lifting devices. Wide industrial and warehousing facilities ensure production process throughout the year.

Raw material for pine bark mulch production is purchased from timber companies throughout Latvia. Only and exclusively Class A pine wood is used for mulch production. High-quality pine bark mulch is obtained by cleaning the pine bark from wood particulates thereafter grinding it, sifting, drying and carefully separating to three different factions – larger sized, medium and smaller sized mulch.

Except for grinding, sifting, drying and sorting, the "Aggregare" Ltd. produced mulch does not undergo any other human processing. It contains no dyes or other chemicals and is completely natural. The finished mulch is conveniently packed in a transportable package bags for 50 and 80 litres and is load to Euro pallets.​

Mulch properties:

  • High-quality pine bark mulch has great decorative features - golden brown pine bark as opposed to, for example, the fir bark, which rapidly blackens, or chopped pine bark, which contains dye and chips look great for a long time. It does not lose its natural colour in exposure to the sun and rains.

  • Pine bark mulch produced by "Aggregare" Ltd. is the entirely natural product. It does not contain any added chemicals and chips.

  • Pine bark mulch is the best cost-effective mulching material: 1 cm of mulch layer decay within one year if mulch was applied in a 5-cm thick layer. This means that about 1 cm of mulch layer should be renewed annually.

  • Proper organic mulching prevents occurrence of harmful organisms, creating less need for watering and weeding, saves a lot of time to be spent for taking care of the greenery.

  • Organic mulch helps fight with weeds, protects plant roots from frost-killing, moreover, contains a variety of useful minerals, which creates favourable conditions for plants and improves the soil.

  • Pure pine bark mulch in your garden in sun heat will bring the pine scent, because except for grinding, sorting and drying, it does not undergo any further human processing.

Scope of application:

Mulch is used as in decorative gardening - flower gardens, parks, urban greenery, paths, play ground and paths tops, as well as in producing agriculture – in trees, shrubs, fruits and berries plantations, for perennial plants beds and vegetable gardens. There is no need to weed and aerate top soil in beds, which surface is covered with bark mulch. In turn, mulch is used indoors for plants and flowers in decorative pots and boxes.
 
Depending on the chosen mulching material, mulch performs a range of practical and aesthetic functions. Pine bark mulch:

  • prevents from weed growing;

  • protects topsoil from erosion and removal;

  • retains moisture in the soil preventing from loss of water in evaporation process;

  • ensures a pleasant and stable microclimate of plants reducing temperature fluctuations in the soil surface;

  • protects plant roots from black frost;

  • promotes favourable biochemical processes and microbial activity;

  • adds humus to the soil acting as a fertilizer;

  • helps to keep the soil loose and forms the good soil structure;

  • furthers plant root development;

  • significantly reduces the time consumed for attending the green zones;

  • improves appearance of green zones.
